This is a randomized, multicenter, single blind, Phase 2 trial of immunotherapy in men with metastatic androgen independent prostate cancer to evaluate sipuleucel-T manufactured with different concentrations of PA2024 antigen
详细描述
This is a randomized, multicenter, single blind, Phase 2 trial of immunotherapy in men with metastatic androgen independent prostate cancer to evaluate sipuleucel-T manufactured with 1 of 3 different concentrations of PA2024 antigen The primary purpose of this study is to compare the changes in CD54 upregulation between each of these 3 groups of subjects.

- •Men ≥ 18 years of age.
- •Adequate hematologic, renal and liver function.
排除标准
- •A subject will not be eligible for participation in this study if any of the following criteria apply.
- •The presence of known lung, liver, or brain metastases, malignant pleural effusions, or malignant ascites.
- •A requirement for treatment with opioid analgesics for any reason within 21 days prior to registration.
- •Moderate to severe disease related pain.
- •Eastern Cooperative Oncology Group (ECOG) performance status ≥
- •Use of non-steroidal antiandrogens within 6 weeks of registration.
- •Anti-androgen withdrawal response.
- •Treatment with chemotherapy within 3 months of registration.
- •More than 2 chemotherapy regimens prior to registration.
- •Initiation or discontinuation of bisphosphonate therapy within 28 days prior to registration.
- •Treatment with any of the following medications or interventions within 28 days of registration:
- •Systemic corticosteroids,
- •External beam radiation therapy or surgery,
- •Dietary and herbal supplements, as well as alternative treatments that have evidence of hormonal and/or anticancer properties (e.g., prostate cancer (PC) -SPES or PC-SPEC) and saw palmetto,
- •Megestrol acetate (Megace®), diethylstilbesterol (DES), or cyproterone acetate, ++Ketoconazole,
- •5-alpha-reductase inhibitors,

- •Treatment with any investigational vaccine within 2 years of registration or treatment with any other investigational product within 28 days of registration.
- •Participation in any previous study involving sipuleucel-T, regardless of whether the subject received sipuleucel-T (APC8015) or placebo.
- •Known pathologic long-bone fractures, imminent pathologic long-bone fracture (cortical erosion on radiography > 50%) or spinal cord compression.
- •A history of stage III or greater cancer, excluding prostate cancer. Basal or squamous cell skin cancers must have been adequately treated and the subject must be disease-free at the time of registration. Subjects with a history of stage I or II cancer must have been adequately treated and been disease-free for ≥ 3 years at the time of registration.
- •A requirement for systemic immunosuppressive therapy for any reason.
- •A history of allergic reactions attributed to compounds of similar chemical or biologic composition to sipuleucel-T or granulocyte-macrophage colony-stimulating factor.

- •Any medical intervention or other condition which, in the opinion of the Principal Investigator or the Dendreon Medical Monitor, could compromise adherence with study requirements or otherwise compromise the study's objectives.
结局指标
主要结局
Cumulative CD54 Upregulation Ratio Between Each of the Cohorts.
时间窗: Baseline, Months 2, 4 and 6.
An analysis of variance model for the log transformed cumulative CD54 upregulation ratio (CD54 upregulation is the fold increase in the final product (FP) from buoyant density separations (BDS) step 65. BDS65 step refers to sample taken after both BDS77 and BDS65 but before ex vivo culture in the presence of antigen PA2024. FP refers to sample taken after ex vivo culture) that includes the antigen concentration cohort as the independent variable was performed. Subjects who received all 3 infusions were included.
